Chapter Text
It was late at night in the House of Lamentation on a Saturday night. No one was moving about, everyone resting in their beds as they slept.
Well, everyone except for Leviathan.
He was wide awake, eyes glued to his computer screen and headphones secured on his ears as a furious blush covered his face.
Levi was playing one of his most favored and secretive games. He kept it hidden deep within his computer, behind file after file. He even went so far as to place a curse on the game itself so that only he can open it. It was imperative that he kept this game all to himself. No one should know about it.
It was a hentai game. One of the most popular in Devildom, in fact. It was extremely customizable, letting you change the appearance of every single character you saw fit, even the main character themselves. He left everything on default when he first got it, not being too terribly interested in that at first.
Then he met you.
Now, the main character looked almost identical to him while practically every other character looked like you. It was creepy, he knew. Even creepier from the fact that he played that game every night for the past week and a half. But he couldn’t help it. He was so attracted to you, so turned on and interested in you. He wasn’t sure how to go about it. He never had feelings for someone this strongly before so he was scared to approach you about it. So, instead, he would fantasize of you and him together. It started off innocent enough with theories of anime themed dates, going to your favorite resturaunt, your first kiss. Over time, his thoughts of you kept getting naughtier and naughtier until he had to do something about it.
So there he was, one hand palming his hard cock through his pajama pants and the other covering his mouth to keep from making too much noise. He had his game on autoplay mode, so his character moved about freely to do as it pleased. They already found you and was kissing you fervently against a wall. The characters were outside and the graphics looked so realistic that he could almost pretend it was real. The soft kissing noises in his headphones were going to drive him insane as he watched. His character brought a hand down between your legs, breaking the kiss to watch you squirm. You were moaning, gripping his arm as he deftly removed your shorts and underwear.
Levi shuddered in his chair, quickly pulling his aching cock from his pants, stroking it slowly. Even the slight touch felt good to him as he watched the characters on screen, wondering if you would react the same way if he did any if that stuff to you.
He looked on as his character divested themselves of their own clothing while yours followed suit. Your character got on their back and spread their legs, waiting paitently as his got down to mouth and suckle between your legs. The resounding moans in his headphones had him gripping his cock harder, stroking faster. He closed his eyes, biting down on a knuckle to try to keep himself quiet. But it felt so good, even better when he imagine what you tasted like. He wondered if you would moan like how he was hearing or would you whimper? Would you talk dirty? Would you just gasp and whisper little utterances of his name?
The thought excited him, imagining him on his knees between your legs as his tongue and lips worked their magic on you. He thought of your face looking down at him, a hand carding in his hair only to tightly grip it and pull. That elicited a small moan from him, precum dribbling down the side his cock and lubbing his hand for a more slick feel.
“F-Fuck,” he whimpered, hearing the moans in his headphones increase. “Fuck, fuck, fuck.”
He finally opened his eyes to see that his character was fucking you against your pile of clothes, his hips snapping rhythmically against yours. He jerked himself to the same rhythm, eyes glued to the screen once again. The angles would change every so often, giving him multiple views to see it all from. As it cycled between them, he clicked among the screen to turn off autoplay mode and instead put it in repeat mode. That way, the scene won’t stop unless he wants it to.
His mind kept drifting back and forth between the fantasies in his head to what was playing on screen. His cock was throbbing in his hand, hot and rock hard. He wanted nothing more than to release his load inside of you, to fill you up and keep going. It felt dirty to think that about you like that, impure. But he’s a demon after all, so was it really so bad?
“Hah, ah, fuck,” his breathing was picking up, his hand stroking faster still. “I want you. I need you. Need to feel you.”
He imagined your face contorted in ecstacy, nodding along to his words as you got yourself off in front of him. He moaned your name, that familiar string tightening in his gut. He was going to come thinking of you again. It was building inside of him, the moans in his ear, the debauchery in screen, his own fantasies. It was all coming together, getting him closer and closer until...
He was coming, voice perhaps a tad too loud for his liking as he moaned your name. He threw his head back, back arching and hips moving forwards and backwards, mouth hanging wide open. He felt his cum land heavy on his on hand and pants, body shaking slightly with the force of said orgasm. It was strong, one of the strongest yet, leaving him almost out of breath.
Yet, even as he came down, he found his cock to still be achingly hard. He could feel his rapid heartbeat in both his chest and cock, his libido not seeming to die down. He needed more. Perhaps just one more time should calm him down.
Levi stood and placed his headphones on his desk, smoothly switching to his demon form. Getting on his hands and knees, he brought his tail up between his legs, thankful it was long enough to be almost his height. He sank down on it, pressing his cock against his sleek tail and wasted no time in humping it.
He set a fast and somewhat sloppy rhythm, thinking of you underneath him. He lost himself in his fantasy, thinking that since he got off, it was now your turn. He tried not to moan too loud, but your name kept slipping off his tongue to the point it felt addicting to say.
“Yes, yes,” Levi moaned, nails threatening to dig into his floorboards. “You feel so fucking good. I need more.”
He paused in his ministrations long enough to form a circle around his cock with his tail that was big enough for it to fit through and snug enough to feel good. As soon as he was situated, he began thrusting into the tight ring he created. It felt amazing.
In his head, you were wanting to choke him, your hands drifting up to his neck to follow through.
“Do it. Choke me.” Levi’s hips stuttered as the words left his mouth but he didn’t stop. “I can take it.”
He slid the end of his tail up his chest and around his neck like he imagined your hands doing, loosely circling his neck before slowly closing in. He could take far more of that than a normal human, choking being the most ineffective way of trying to kill him. Yet, it heightened his pleasure to feel his breathing be cut off. His head felt detached from his body, as if it were floating while his body writhed in pleasure.
He was humping his tail with unmatched speed, eyes rolling back with the pleasure. He needed this. He needed it so bad. You were all he could think of lately, all that crossed his mind. He wanted to fuck you hard. Wanted to hear you cry out for him and only him, so loud that his brothers would hear and know that you were claimed by him.
He panted out his nose at the thought of you screaming his name, your tight hole hot and inviting. He’d make you feel good, make you addicted to him like he was to you. Fuck, he couldn’t last much longer.
Levi wanted to announce that he was going to come but he kept his tail tight around his neck. All that came out were choked gasps and garbled messes of words.
His eyes rolled back as he came for a second time that night, his hips faltering in their rhythm to slowed thrusts, hips smacking against his tail lewdly as he came on himself and the ground. His nails shakily raked against the ground, tail squeezing one last time around his neck before finally loosening. Levi sucked in a greedy breath, his tensed body finally relaxing. His whole body felt tingly, sensitive. He couldn’t remember the last time playing with himself felt so good.
Sitting up on his knees, he looked down to see the mess he made, knowing he’d have to clean up soon. That could wait for a little bit though. His body was tired from the second release, his breathing shaky at best and heartbeat raging. His cock was finally soft, though, so that was a good thing.
He stayed like that for a short while, trying to calm down before he finally got up on wobbly legs to clean up. He shut his game off, turned the monitor off, and curled up in his bathtub to sleep.
The ever present hum of his computer coupled with the etheral glow of his fish tank and relaxed body, he knew he’d be sleeping late into the morning. He curled his tail up against his front, wishing it were you instead.
“Goodnight,” he mumbled, kissing the tip of it as if it were your forehead, already drifting off. “Sleep tight.”
